I have a branch pretty close for this, but could use some guidance before I make it a PR.

My change uses the existing skipSaveParticipants option. However, this would also skip CodeActionOnParticipant and ExtHostSaveParticipant, which—if I understand correctly—wouldn't necessarily relate to formatting.

1. Being personally unaware of other use cases for save participants, I'm not sure whether this is an acceptable solution or if participants would need to be categorized so we can specifically skip only those relating to formatting.
2. I suspect that "participants" is not a well-recognized term for users and "Save without participants" would not be intuitive. What should the user facing name for this command be? Is there an existing term for this somewhere?
3. I'm unclear on the difference between fileActions.ts and fileActions.contribution.ts when adding a command to the palette.

I definitely think this should be built-in to VS Code.

Until then, here's a great workaround: https://marketplace.visualstudio.com/items?itemName=Gruntfuggly.save-without-format#overview

There is now a new command "Save without Formatting" with the keybinding Cmd+K S. If someone has a better name, feel free to suggest (initially I had "Save without Participants" but that seems a bit too technical).

Thanks! 🎉🎊🍕🎈

Are there extensions with participants unrelated to code formatting in common use? If so "Save without Transforms" or "Save Verbatim" might also make sense. Otherwise, "Save without Formatting" sounds good.

@coreh yeah "Save without Formatting" would even mean that any extensions cannot participate even if not doing any formatting.

But my rationale was to cover the 99% case of why one would actually use that action in the first place and that is probably to prevent any kind of format to happen.

Maybe "Save without Extensions". This will disable all kind of code actions that run on save and that's actually a thing.

I am not convinced. People might confuse this to "save the file without a file extension". I am not sure there is any use case for using this command other than preventing any formatting from happening, so I would stick with the name or something similar in that direction.

@bpasero I tried to save a file without formatting following your suggestion: "Cmd+K S", but instead of saving without formatting, VSCode just brought up the menu for key bindings. (VSCode can be so confusing at times. I used to happily use shift+option+s to achieve this, then it stopped working, and now I can't seem to get a simple answer for how to achieve this. Would really appreciate some guidance here!)

@vivaldus looks like the keybind changed...

Remember you can usually (if not always) search within Visual Studio Code. Yay for VS Code being such a useful tool.
